Preserving the consumed energy of each node for increasing the network lifetime is an important goal that must be considered when developing a routing protocol for wireless sensor networks. The main objective of cluster-based routing protocol is to efficiently maintain the energy consumption of sensor nodes by involving them in multi-hop communication(More)
The main challenge facing us in the design and conception of Wireless Sensor Networks (WSNs)is to find the best way to extend their life span. The clustering algorithm is a key technique used to increase the scalability and life span of the network in general. In this paper, we have proposed an energy aware cluster head selection algorithm, for(More)
A MAC protocol is required in sensor networks to coordinate the sensor nodes' access to the shared medium. Designing power efficient MAC protocols is one of the ways to prolong the lifetime of the network. In addition to energy efficiency, latency and throughput are also important features for consideration in MAC protocol design for sensor networks. In(More)
Wireless sensor networks (WSN) consist of spatially distributed autonomous small devices, often called "motes", which cooperatively monitor, collect and exchange data from the surrounding environment. In this paper we simulate and evaluate the performance of different radio channels in terms of Energy efficiency, Latency, Throughput, and Number of Drop(More)
Wireless Sensor Networks (WSNs) consist of a large number of energy-limited sensor nodes that are densely deployed in a large geographical region. The main challenge facing us in the design and conception of Wireless Sensor Networks (WSNs) is to find the best way to extend their life span. Therefore, proper energy management technics and communication(More)
